According to a memo sent out to current license holders of Intactix Portfolio, 7.6.1 is now available for ordering. Nothing was mentioned about the software being available for download which became an option for version 7.6.0 but I would think that this is still an option. Just contact JDA support for that link.
Since this is a service release this may not be something you need to run out and install immediately. The memo indicated that most of the changes will affect Planogram Converter, Floor Planning, Planogram Generator, EIA and the PEM feature in Space Automation.
